To make one, players need to have a cut emerald in their inventory. Operate the workbench next to Apprentice Clerval in the basement after speaking with Wizard Shug about the process and taking 20 essence to Clerval.

Players must create two enchanted emeralds to complete the quest. It has no other uses other than during the quest, and cannot be made after completing it.

Strangely, no runes are required to enchant an emerald on Clerval's workbench, perhaps due to the nearby Enchanting Chamber.
